I don't really care either way, but would it maybe work out as a compromise to have a separate thread for XIV-related stuff? The way I see it, the discussion would reach more people because a lot of folks avoid Random Thoughts. And it would fit more cleanly into the forums, as most people post in more FFXI-focused threads when they want to discuss XI-related stuff.
It's one thing to post a funny FFXIV meme or shout a relevant story into the void, but any time someone wants to start a legitimate discussion that could go to a different thread. (EDIT: Granted, most of the time it starts out as a "random thought" and evolves into a discussion on its own)
Alternatively, I did make
a suggestion a while back about the concept of hiding individual posts. If someone doesn't like what they see, they can more easily ignore it without blocking the entire user.
